A reader writes:
You are right about the protuberant nipples. I grew up on a small family hog farm. Nipples on a pig are not an indication of sex, especially if it is a young male pig deprived at an early age of his - ahem - manhood, which I presume Ralph to be. Hence, the term my dad always used: “Worthless as teats on a boar hog.”
The more important indicator of Ralph’s true sexuality can be seen between his worthless nipples about three-quarters of the way back toward his hindquarters. He is quite elongated in that postcard shot but I think I can just make out the only thing visible in that picture (and most likely, the only thing visible on poor emasculated Ralph) which determines that Ralph, is, actually a Ralph. Odd that in the Hallmark Goo post, even that has been erased. Poor Ralphie.
